Vuex安装

执行：

npm install vuex

因为vuex依赖Promise但是IE没有实现Promise【控制台输入window.Promise检查

】，所以添加使用一个polyfill的库es6-promise:

执行：

npm install es6-promise

将下列代码添加到你使用 Vuex 之前的一个地方：

import 'es6-promise/auto'

app.js:

/**
* First we will load all of this project's Javascript dependencies which
* includes Vue and other libraries. It is a great starting point when
* building robust, powerful web applications using Vue and Laravel.
*/
require('./bootstrap');
window.Vue = require('vue');
import 'es6-promise/auto'
import Vuex from 'vuex';
Vue.use(Vuex);
/**
* The following block of code may be used to automatically register your
* Vue components. It will recursively scan this directory for the Vue
* components and automatically register them with their "basename".
*
* Eg. ./components/ExampleComponent.vue ->
*/
// const files = require.context('./', true, /\.vue$/i)
// files.keys().map(key => Vue.component(key.split('/').pop().split('.')[0], files(key).default))
Vue.component('example-component', require('./components/ExampleComponent.vue').default);
/**
* Next, we will create a fresh Vue application instance and attach it to
* the page. Then, you may begin adding components to this application
* or customize the Javascript scaffolding to fit your unique needs.
*/
const app = new Vue({
el: '#app',
});

执行：

npm run watch-poll
